Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE `i ARTHUR DEAKIN, F MONTREAL, QUEBEC, CANADA CHAIN coNvnYEn Application mea september 21, 1927. serial Nn. 221,015.

` links of a conveyer chain between which are mounted rollers of solid construction rotatably mounted on bushings surrounding pins passing through the links. The rollers are adapted to engage with a rail or guide. It

` has been found that the main wear takes place on the bore of the rollers and that great difficulty has been encountered in replacing the solid rollers, as every outside link has to be removed thus weakening the construction of the conveyer.

According to the present invention the above difficulty has been overcome by providing split rollers which` are so constructed that the load is transmitted directly through the The rollers have means formed `therein to position the sections ofgthe rollers with respect to one another.

In the drawings which illustrate my invenshown in assembled relation.

`Referring more particularly to the drawings, 11 designates carrier plates which are secured to the inner links 12 of a conveyer. Angles 13are shown as the connecting mediumfor illustrative purposes. Connecting the outer links 14 with the inner links 12 are the pins l5, and rotatably mounted thereon are the rollers `16. Bushings 17 are placed between the rollers and the pins. The rollers run on a suitable track 18 and engage with V55 the teeth 19 of sprockets 20, which may be rotated by any suitable means. The material to be bakedlis mounted on the plates and is carried into the oven (not shown), the direction of movement of the conveyer being in the direction of the arrows 21. My improvement lies in themspecial construction of rollers, a detail of one of which is shown in Figures 3'to 5 inclusive. The rollers are formed in two sections 22 and 23. The bore is split centrally along the line 24, but section 22 has projections 25 which fit into cut-away portions 26 forming a Step joint between the sections. Section 22 is provided with a recessed aperture 27 to receive the heads 28 of screws 29, the threaded portions of which engage with threaded apertures 30 formed in the section 23. The screws hold the sections Vtogether while the rollers are bored and turned on their faces 31. The saine screws are used for holding the sections in position around the pins 15 and bushings surrounding same. Dowel pins 32 may alsobe provided to prevent shearing of the screws due to side thrust. These pins 32 fit into recesses33 and 34 formed in adjacent faces of the sections of the roller. j

It will be seen that when any undue wear takes place on the roller, the same may be removed by unscrewing the pins and pulling the sections apart and a new roller may be quickly and easily installed without interfering with the working of the machine to which the conveyer is attached. By stepping therroller joints, the weight is` transmitted through the sections of the roller and is not taken up on the connecting screws or the links, plate su ports secured thereto, pins passing through the adjacent ends of the links and split rollers rotatably mounted on the pins, said rollers having radially stepped joints arran ed at opposite sides of and paralleling the ores of the rollers and means to hold the portions of the roller together.

2. A chain conveyer roller divided longitudinally to provide a pair of separable sections, each section being provided with a cen-- tral longitudinally extending recess semicircular in cross section and adapted to register with the corresponding recess of the'other section to form the completebore of the roller when the two sections are secured together, themeeting faces of the two sections extendl in at opposite sides of the bore being made su stantially Z-shaped to provide a stepped joint between the sections and fastening ydevices for securing said sections together.

In witness whereof, I have hereunto set my hand.

ARTHUR DEAKIN.
